FLUE TOOL.

Application filed March 24, 1923. Serial No. 627,368.

To all 'whom t may concern:

use in the removal and replacementl lof the tubes of boilers.

An important object 0f the invention is IVto provide in a single toolmeans for loosening and crimping a boiler tube so that the same may beremoved from the opening of the crown sheet, together with means wherebya new tube when installed may be initially expanded so that the expanderproper when employed with the tube may be readily entered.

A still further object of the invention is t0 provide a device of thischaracter which is slmple in construction, may be cheaply produced andwill be durable and efficient in service. y

These vand other objects I attain by the construction shown lin theaccompanying drawings', wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is a sideelevation of the tool constructed in accordance with my invention; i f

Figure 2 is an end elevation thereof; Figure 3 isan edgee'levation'thereof; Figures 4, 6 and 8 show various manners of.employing the tool; and

Figures 5 and 7 show the resulting forvvmation of the tube.

Referring n'ow more particularly to the drawings, `numeral 10 designatesa tool shank, liattened and broadened at'one vend, as indicated at 11,this end of the tool is furcated, as at 12, to provide long and shortcutters 13 and 14. The cutter 13 is'substan` tially tri-angular in crosssection,.` the inner face thereof being in the form of a cutting edge,as indicated at 15. The short cutter 14 is formed to provide a spadechisel point, as indicated at 16, the wall of the furcation being flatlyground, as indicated at 17, and meeting abeveled face 18 set angularlyto the outer wall of the broadened end of the Shank to form a spadepoint.4

This ground face 18 is at such an angle .that the plane in which itliesextends in advance of the forward extremity of the long cutter 13, thuspermitting use of the cutting edge 16 against .the plane, with the face18 lying in the plane and the point 19 of the long cutting edge clearingsuch plane. Intermediate its ends the shank 10 is provided upon a sideface thereof with lan outstanding shoulder 20, the lower face of whichis disposed at right angles to the axis of the shank and curvedtransversely of the shank, as more clearly shown in Figf ure 3.

In the use of the tool for removing a tube T from u crown sheet S, thespade point 16 is abutting against the bead B formed in rolling the tubein position with the usual expander with the face 18 abutting the crownsheet S. By a few sharp blows with a hammer the tube can be deformed atthe point of engagement, as indicated in Figure 5, so that a space isformed between the formed tube and the adjacent edge of the opening ofthe crown sheet, permittingthe t insertion of the long cutter 17. Thiscutter is inserted, as indicated in Figure 6, with the curved face 21thereof.. in engagement with the crown sheet at the edge of the openingand the cutter edge 15 thereof engaging the deformed portion of thetube. By a few sharp blows with the hammer this long cutting edge isformed into the opening of the tube with the result that the tubeiscrimped inwardly, asmore clearly shown in Figure 7, and so reduced insize that it maybe readily forced ythrough the opening of the crownsheet. ln the use of the tool in installing new boiler tubes. after thetube has been inserted and extendedthrough the crown sheet. the shoulder20 is engaged interiorly of the tube. asindicated in Figure 8, andstruck several hard blows with the hammer; with the result that theextended wall of the tube is flared outwardly in such manner as topermit ready insertion of the usual expander not herein Shown.

It. will be obvious that a tool of this character is capable ofperforming a plurality of functions, each necessary in the applicationand removal of boiler tubes, and will be of' great assistance'tomechanics performto rmit the insertion of the expander. I desire it -tobe'understood that I may make slight changes in the construction and in.

the combination and arrangement` of the several parts, provided thatsuch changes fall Within the scope of the appended claims.

1. The tool for the'purpose described, a shank flattened at one end andfurcated to provide long and short cutter arms, the long cutter armbeing provided upon its inner surface with a, V-shaped cutting face andshort cutter arm being provided with a.- spade point, formed by thejuncture of two beveled surfaces, one 'of which is disposed in a planeintersecting the axis of the tool .and passing in advance of extremeforward point of the long cutter.

2. The tool for the purpose described,`a. shank attened at'one end andfurcated -to provide long and short cutter arms, the long cutter armbeing provided upon its inner surface with a V-shaped cutting face andshort cutter arm being provided with a spade point, formed by thejuncture of two beveled surfaces, one of which is disposed 1n a planeintersecting the axis of the tool and passing in advance of extremeforward point of the long cutter, said shank being provided upon itslside wall with beading shoulder.

3. The tool for the purpose described, a shank attened at one end andfurcated to provide long and short cutter arms, the long cutter armbeing provided upon its inner surface with a V-shaped cutting face yandshort, cutter arm being provided'pwith a spade point, formed by thejuncture of twobeveled surfaces, one of which is disposed signature. p Y
